Coverting equations from word to PDF in Acrobat

I am encountering an issue with character encoding and equations created in MS word. I have googled this to death and wanted to see if someone has a solution for us. The issue seems to be the font Cambia Math, but I can't figure out how to resolve it.

 

In the past we converted equations to images and used alt text for the reader, but it is inefficient. 

 

I am running Windows 10 and the continuous release version of Acrobat Pro.
